This USB 2.0 to DC pigtail cable lets you power 5 V or 12 V devices directly from any USB-A port using a 22 AWG tinned-copper extension lead. It is built for powering small fans, LED strips, battery packs, and DIY electronics from a USB power source, with a male DC plug ready to terminate the device side. Available in 15, 30, 50, 100, 150, and 200 cm lengths in black or white, with PVC insulation rated 80 °C and 300 V.
Product Description
This is a 22 AWG USB 2.0 to DC pigtail cable that takes power from a standard USB-A source and delivers it through a male DC barrel plug at the load end. It is designed for low-power 5 V or 12 V devices that draw up to the USB port's available current, and is most useful for replacing damaged USB power leads, extending the reach between a USB power bank and a small load, or building custom DIY power runs from laptops, hubs, or wall-mount USB chargers.
The conductor is tinned copper, which keeps contact resistance low over time, and the insulation is PVC rated to 80 °C and 300 V. The black or white outer jacket choice is a finish option only — electrical performance is identical between the two.
Key Benefits
- Plug-and-play USB-A power source — no soldering required for plug-and-play replacement
- Tinned copper 22 AWG conductor for low contact resistance and long service life
- PVC jacket rated 80 °C and 300 V — safe for indoor and enclosed-equipment use
- Six length options from 15 cm to 200 cm cover both short jumpers and full desk-length runs
- Black and white finishes match cable management on either dark or light equipment
Key Features
The first feature worth flagging is the USB 2.0 source side: this cable draws from a standard USB-A port, so any phone charger, laptop port, USB hub, or power bank can serve as the supply, with no separate adapter required. The 22 AWG conductor is sized for the typical 5 V / 1–2 A or 12 V / boosted USB output range, with PVC insulation that stays flexible at room temperature and resists abrasion against panel edges. The DC barrel plug at the device end is the standard 5.5 x 2.1 mm form factor that fits most low-power 5 V and 12 V consumer devices.

What's Included
- 1 x USB 2.0 to DC male barrel jack pigtail cable assembly (per selected variant)
Compatibility & Applications
This cable is compatible with any USB 2.0 Type-A power source (USB-A wall chargers, laptop USB ports, powered hubs, power banks) and any 5 V or 12 V device that uses a 5.5 x 2.1 mm center-positive DC barrel jack and draws no more than the source USB port can deliver. Typical applications include:
- Small USB-powered fans
- LED strip lights and lamps
- Battery pack powered DIY projects
- USB gadget power extensions
- Hobby electronics and prototyping
Not compatible with: 5.5 x 2.5 mm jacks (different inner diameter), center-negative devices (polarity reversal will damage the load), and devices that require more current than the USB source port can supply.

Frequently Asked Questions
What voltage will this cable actually deliver, 5 V or 12 V?
The cable itself is voltage-agnostic. Standard USB 2.0 ports output 5 V at up to about 0.5 A (USB 2.0 spec) or 0.9 A (USB 3.0). For 12 V output you need a USB source that explicitly supports voltage boosting, such as a USB-PD power bank with a trigger cable, or a USB-C PD source. With a normal USB-A wall charger you will get 5 V at the device end.
How much current can this cable safely carry?
The 22 AWG conductor is conservatively rated for 3 A continuous in PVC insulation at room temperature, well above what a typical USB 2.0 port can deliver. The current limit in practice is set by the USB source, not by this cable.
Which length should I choose?
15 cm and 30 cm are best for short jumpers between a power bank and a device on the same desk. 50 cm and 100 cm are typical for desktop and shelf installations. 150 cm and 200 cm cover floor-to-shelf or wall-to-monitor runs. Longer runs at 5 V will see slightly more voltage drop, but it remains within tolerance for most LED and fan loads.
How fast does shipping take?
Orders are dispatched from regional fulfillment partners in North America, Europe, and Asia. Typical delivery is 5 to 15 business days depending on destination country, with tracked shipping included. Specific timelines per destination are listed in the Shipping Policy.
How does this USB pigtail compare to others in its category?
Within the USB-to-DC pigtail category, the meaningful comparison points are conductor gauge, jacket flexibility, and length range. This product uses 22 AWG tinned copper, PVC rated to 80 °C and 300 V, and offers six length options from 15 cm to 200 cm — the configuration that fits the broadest set of bench and desktop applications and drives the lowest return rate within our small-electronics category.
